SureFit Tour Weightkit for 910 driver

[Bratty]

Hi all,

I've done a few searches and couldn't find a post here already, but apologies if I've simply missed it.

What does changing the weight in the 910 actually do? The blurb says "it gives you the desired weighting effect".

Great. But what does that actually mean? Does it help with squaring the clubface, does it help tempo, does it promote a particular type of shot?

Any help gratefully received. Cheers!

It must change the swing weight, but that could be done with a heavier shaft.
I expect it moves the centre of gravity about, to promote a higher or lower launch, without changing the loft.
